In Himalayas, the ________ temperature with increasing altitude causes the change in vegetation.

Correct option is D

Sol. The correct answer is (d) decreasing.
· In the Himalayas, as altitude increases, the temperature decreases.
· This decrease in temperature significantly impacts the types of vegetation that can survive at different altitudes.
· Lower altitudes in the Himalayas have tropical and subtropical forests.
· As the altitude increases, the temperature drops, leading to temperate forests, followed by sub-alpine and alpine vegetation.
· The treeline, above which trees do not grow, is determined by this temperature decrease.
· Beyond a certain altitude, the temperature is too low for any vegetation to thrive, leading to snow and ice-covered peaks.
